Find the perimeter of the shape with vertices (2, 3), (5, 3) and (5, 7).

Effectus [21]

Answer:

12 units

Step-by-step explanation:

To find the perimeter given vertices, find the distance from one point to another.

Step 1. Find the distance between (2, 3) & (5, 3)

Answer: 3 (in this case) because for 2 to get to 5, it’s 3 units

Step 2. Find the distance between (5, 3) & (5, 7)

Answer: 4 (in this case) because for 3 to get to 7, it’s 4 units

Step 3. Find the distance between (5, 7) & (2, 3)

Answer: 5

Step 3 explanation: In image.

Step 4. Add all the distances between the points.

3 + 4 + 5 = 12 units

The perimeter is 12 units

43. Simplify (k – 5) - (k2 + 8).

lesantik [10]

Answer:

(D) -k2 + k - 13

Step-by-step explanation:

Pulling out like terms :

2.1 Pull out like factors :

-k2 + k - 13 = -1 • (k2 - k + 13)

Trying to factor by splitting the middle term

2.2 Factoring k2 - k + 13

The first term is, k2 its coefficient is 1 .

The middle term is, -k its coefficient is -1 .

The last term, "the constant", is +13

Step-1 : Multiply the coefficient of the first term by the constant 1 • 13 = 13

Step-2 : Find two factors of 13 whose sum equals the coefficient of the middle term, which is -1 .

-13 + -1 = -14

-1 + -13 = -14

1 + 13 = 14

13 + 1 = 14

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

-k2 + k - 13

Angela’s savings account balance was 133.10 after 3 years. What would the balance be after 5 years if the interest rate remains

Novay_Z [31]

In this question , we have to use compound interest formula, which is

$A= P(1+r)^t$

Here Amount after 3 years = $133.10

Rate of interest = 10%=0.1

TIme =3 years

So we get

$133.10= P(1+0.1)^3 \\ 133.10 = P(1.1)^3 \\ 133.10 = 1.331P \\ P = 100$

Now we have principal, P = $100,

Rate of interest, r =0.1

Time, t = 5 years

So we will get

$A = 100(1+0.1)^5 \\ A = 100(1.1)^5 \\ A = 161.051$

So the balance after 5 years will be $161.05 .
